IMPROVEMENT IN WHEELS FOR INDEXING.

Specification forming part of Letters Patent No. 157,163, dated November24, 1874; application filed September 9, 1874.

To all whom it may concern:

Be it. known that I, HENRY H. EDWARDS, of Grand Rapids, in the county ofKent and State of Michigan, have invented certain new and usefulImprovements in Wheels for Indexing and Gilding; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part of thisspecification.

j My invention consists of an indexing-wheel having an interior annularspace, in combination with the removable adjusting open bands or ringsof uniform thickness, wrapped one upon the other upon the base-wall ofsaid space to form the type-seat, and give the series of type an equalprojection from the annular seat, whereby the type are projected fromthe outer periphery to form circles corresponding to diierent lengths ofpages. The separate bands being of uniform thickness, and seatedconcentrically upon a concentric seat, renders such adjustmentconvenient and easily made, and, by a construction and combination ofdevices, well and cheaply adapted to the indexing-wheel.

In the accompanying drawings, Figure 1 represents an elevation ot' myimproved printing-and gilding wheel; Fig. 2, a section thereof, and Fig.3 a view with the side cap removed to i show the manner of setting thetype, and of increasing or diminishing their circumferential distancesapart.

The wheel A is driven upon its journal a by the curved reach B, and thiswheel has openings b, which extend radially from its periphery, and openinto an annular space, O, on the inner face of the wheel. The base orinner Kwall C' of this space is embraced by one or more bands or rings,d, fitted within the annular space, and upon which rest the bottoms ofthe types e, which extend radially there from. The wheel is completed bya cap side piece, A,ahub,D,whereof carries the journalbearing f for thehandle B. This cap is secured to the face of the Wheel, so that it maybe readily removed to permit of the insertion ing the number ot' therings d, as, if a ring be added to those in the space G between the typeand the base C of said space, the types e will be all extended in theirrespective radiuses, and their circumferential spaces apartproportionately increased. If a ring be removed, the reverse takesplace. The bands are not continuous, but are interrupted, and their endsare confined in the parts free from the controlling pressure of the typeby a wedge or wedges, h, driven between said rings and the outer wall ofthe annular space. The bands d must be of uniform thickness throughouttheir length. The removable cap not only affords facility for adjustingthe type, but for heating the wheel of typeindependent of the cap andthe carrying reach, when it is desired to print gilt letters, and theseparts are thereby saved from injury. The wheel is of metal, and used inthe manner well understood by book-finishers.

I/Vhen the types do not require adjustment, they are seated and clampeddirectly upon the inner wall of the annular projection c of the wheel.

I claim- In an indexing-wheel the interior annular space C, and theconcentric seat C', in combination with the removable adjusting bands orrings d, wrapped one upon the other upon the base-wall C of said space,to form the typeseat, whereby the type are projected from the .peripheryto form circles corresponding to the different lengths of pages.

In testimony that I claim the foregoing I have affixed my signature inpresence of two witnesses.V
